for advantageous use by campers, autom0 bili sts, and others who may desire a stool which can be easily collapsed mto small space for transportation.

The object of my invention is to provide a device which While it may lie-conveniently.

used as a stool and collapsed or knocked down for convenient transportation, may also be used'for other purposes than as a seat, as, for instance, as a bowl or basin for holding liquids, washing and the like.

The features of my invention which I believe to be new "may be determined by an inspection of the specification and the claims terminating the same.

The accompanying drawings show a practical embodiment of my invention.

Figure 1 is a sectional elevation through the device in use as a stool, in its set up position. v

Figure 2 is a similar view of the device when set up for use as a bowl or basin.

Figure 8 is a transverse section taken mainly through the means employed for binding the legs together.

Figure 4 is a similar view where a modified construction is employed, which uses only three legs instead of four.

Figure 5 is a side view of one of the legholding members which engage the center portion of the legs.

The seat member ofthe stool which forms the subject of this invention is designed to be made of metal orof such other material as at times is substituted for metal in analogous shapes, and is in the formof a dish or bowl. The natural shape for this would be of circular outline. The bottom'portion 1 may be made fiat or dished as desired. In the device as shown in the drawings this is shown as being flat. The flanges I pre- Fer to make of rather material extent so that the seat member may be used as a substantial dish or container for any liquid or other article. This flange is also preferably pro-' vided with a rollededge as 11, thisgiving it finish and additional strength. T This seat member is provided with means for attaching thereto the legs by which it is" supported. In Figures 2 and 3 it is contemplated that these legs will be four in nun ber, while Figure 4 contemplates the use of three legs. Distributed about the. outer edge of the bottom section are leg-engaging means consisting of vhollowthimbles which. are pressed from the material of which the bot-' tom isformed so that at one side thereof theyarein the form of projecting lugs of circular outline,-,while o'nfthe other side they form sockets. 1

The legs-2T prefer'to make of cylindrical section: At o'neend they are provided with a tip of reduced diameter, this being adapted to enter the socket which in the embodiment of the device illustrated is at the outer side of the bottom member. The other end of the legs are each provided with a sleeve 21 of such size as to slip over the projecting portion of the thimble, as is shown in Figure 1. These leg-holding thimbles are placed at an angle such that inthe one case the legs will cross as shown inFigure 1, and in the other case will occupya diverging position as shown in Figure 2. The engaging portions of the legs and of the top may, when desired, be threaded for positive engagement. y

The device b y which the legs are engaged at or about the center of their length to hold them together is illustrated in Figures 3 and 4, one being adapted for holding four legs and the other three. Each. of these devices is alike'in its principles of construction. They each employ a set of plates, as 3, these being four in number where four legs are employed, and three in number where three legs are employed. Along the edges of these plates 3 are provided engaging flanges so that. they may be held together. These flanges project in opposite directions of the plates. One of these, as 32, if a flange I 100 i as between. the upper and. the lower halves hali of the plate and the rightangled flange upon the other. Two orniore of the plates may thus be engaged by sliding movement so as to engage these parts with each other and bind them all securely together.

Secured to each one of the plates-3- is a thim'ble or ring member 4: which is adapted to receive and hold the legs. These are held in place by a rivet as 4:0, which Will permit swinging of the leg so that the legs may all be swung into position parallel with each other, ii this bedesired. It is not intended that the rings a should fit tightly enough about the legs to permit turning of the legs, if they are to be secured to the seat member by screwing thereon as previously mentioned. The projection of the locking flanges by which the plates 3 are held together is such that they will act as stops to prevent savinging of thelegs: 2 through too great an angle. lVith the device assembled as shown in Figure l a substantial seat is formed. 'The seat member 1 may be used alone as a basin or' holder for any material desired. This maybe done without using the legs. At the I same time, the legs may be inserted therein after the manner shown in Figure 2 so as to support this basin raised above the ground. When so employed it forms a convenient Wash basin. The same basin may also be used for cooking, if desired.

It is my intention to make the seats or howls with their side flanges 10 sloping or tapering enough so that two or more may be nested for packing if desired.

hat I claim as my invention is:

l. A knock-down seat comprising a basinlike seat member having leg-securing means distributed about the outer edge of its bottom and consistiiur of hollow thimbles integral with the body of the basin and legs at one end adapted to enter the thimble and v at its other end to fit over the thimble.

'2. knock-down seat comprising a seat member provided with means for supporting legs therewith, four legs adapted to engage the seat While maintaining a crossedv position. and a leg confining member comprising a. central body composed-of a set of plates having sliding interlocking engagement with each other and means for pivotally securing a 'le rto each of said plates.
